VITAMIN A RICH FOODS AND THEIR CHEMICAL PROPERTIES

Vitamin A is a fat-soluble micronutrient essential for vision, immune system function, cell differentiation, and growth. It occurs in two primary forms: preformed vitamin A found in animal products and provitamin A carotenoids found in plant sources. This article analyzes the chemical characteristics of vitamin A and evaluates major food sources rich in this vitamin. Particular attention is given to the molecular structure, chemical properties, and transformation of carotenoids into biologically active retinol in the human body. The study also discusses the nutritional importance of vitamin A-rich foods and their role in preventing vitamin A deficiency.
